INTEGRATED USE OF ORGANIC AND INORGANIC FERTILIZERS IN WHEAT AND THEIR RESIDUAL EFFECT ON SUBSEQUENT MUNG BEAN
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 8
Abstract
Application of organic materials along with inorganic fertilizer helps in proper nutrition of crop and maintenance of soil fertility. integrated effect of organic and inorganic fertilizers on growth and yield of wheat and investigate their residual effect on subsequent mung bean was evaluated at Livestock Research and Development Station Surezai, Peshawar for two crops seasons 2010-11 and 2011-12. Experimental treatments were three organic fertilizers levels of poultry manure (2, 4 and 6 ton ha-1) and three farm yard manure (2, 4 and 6 ton ha-1) and two inorganic nitrogen levels (60 and 90 kg ha-1) along with control were applied to wheat crop. Mung bean was cultivated on the same plots after harvest of wheat without application of fertilizers to investigate the residual effect of these fertilizers on growth and yield of mung bean. Poultry manure, farm yard manure and nitrogen significantly affected spikes m-2 grain yield and harvest index of wheat. Higher spikes m-2, grain yield was observed with application of 6 tons poultry manure, 6 tons farm yard manure ha-1, and 90 kg N ha-1 while higher harvest index was recorded in control. Residual effect of the entire organic and inorganic combination also significantly affected crop growth rate, pods plant-1 and biological yield of mung bean. In case of mung bean more crop growth rate, podss plant-1 and biological yield (kg ha-1) was also observed with the residual effect of 6 tons poultry manure, 6 tons farm yard manure ha-1, and 90 kg N ha-1. Higher yield was observed with integrated application of organic and inorganic fertilizers in the ratio 6 ton poultry manure, 6 ton farm yard manure ha-1 and 90 kg N ha-1. Mung beans rely on the residual fertilizers applied to wheat. It is concluded that a ratio of 6 ton poultry manure, 6 ton farm yard manure ha-1 and 90 kg N ha-1 is recommended for higher yield in wheat.
